Carnival Glory achieved a perfect score on its most recent US Public Health inspection. The inspections are conducted semi-annually on a surprise basis. Those are becoming more common since ships are being built specifically to make them easier to maintain USPH standards, but there's another part to Carnival Glory's perfect score. This is the second time in the last three inspections that Carnival Glory has achieved that coveted 100%. Even the time it didn't quite make perfect, it still scored a 97. Fleetwide, over the past year, the Carnival fleet has averaged a score of 93.
